testthat (version 0.9.1)

auto_test: Watches code and tests for changes, rerunning tests as appropriate.

Description

The idea behind auto_test is that you just leave it running while you develop your code. Everytime you save a file it will be automatically tested and you can easily see if your changes have caused any test failures.

Usage

auto_test(code_path, test_path, reporter = "summary", env = test_env())

Arguments

code_path

path to directory containing code

test_path

path to directory containing tests

reporter

test reporter to use

env

environment in which to execute test suite.

Details

The current strategy for rerunning tests is as follows:

• if any code has changed, then those files are reloaded and all tests rerun
• otherwise, each new or modified test is run

In the future, auto_test might implement one of the following more intelligent alternatives:

• Use codetools to build up dependency tree and then rerun tests only when a dependency changes.
• Mimic ruby's autotest and rerun only failing tests until they pass, and then rerun all tests.
